Abstract:
A picture decoding method is provided for decoding coded picture data. The decoding method includes decoding coded picture data to obtain a first transform block and an adjacent second transform block in a reconstructed picture having a plurality of blocks forming a moving picture image. The decoding method also includes determining whether the first transform block is located inside a motion-compensation block in which the second transform block is located. The decoding method further includes performing a filtering on pixels in a block boundary between the first and second transform blocks when the first transform block is located outside the motion-compensation block in which the second transform block is located, and performing no filtering on the pixels in the block boundary between the first and second transform blocks when the first transform block is located inside the motion-compensation block in which the second transform block is located.
